SX1701B – Datasheet
Highly linear wideband LNA
Multi-channel, single-ended to differential conversion
GENERAL DESCRIPTION
The SX1701B is an integrated LNA operating over a
wide frequency range from 40 MHz to 2.5 GHz. It is
optimized for high OIP2 and OIP3 with minimum current
consumption. It also performs a single-ended to
differential conversion.
Two independent output channels are available and the
gain of each may be adjusted independently.
APPLICATIONS
Digital Set Top Boxes (Satellite and Terrestrial)
CATV Distribution Systems
Active Splitter
Data Communications Systems
Active Balun
TYPICAL APPLICATION
KEY PRODUCT FEATURES
Single-ended input / Dual differential outputs
Independent programmable gain for each channel: 6,
12 and 18 dB
High Linearity: OIP2 of 57 dBm and OIP3 of 22 dBm
Noise Figure of 7 dB
75 Input impedance
100 differential output impedance
Current consumption of 130 mA with one channel
enabled
ESD protection (Normal ESD handling procedures
